Leaf Spectra and Weight of Species in Canopy, Subcanopy, and Understory Layers in a Venezuelan Andean Cloud Forest

Table 6

Correlation between spectral variables for all spectra (absorbance 𝐴, reflectance 𝑅, and transmittance 𝑇). High values (>0.85) are highlighted in bold. Italics denote high correlation between bands or between features. Underlined cells show correlations of FIf with other feature variables.
